traveler

(Sometimes spelled as "traveller" or "travelor.") A complete curtain assembly consisting of track, carriers, rigging, and drape intended to move horizontally. May be either one-way, or more commonly bi-parting. The end of the track where one interacts with the operating line is the live end, the opposite is the dead end. The drapery is usually sewn with 50-100% fullness from 16-28 oz. velour.
